UNITED STATES PATENT Orrlcnt WILLIAM SCHGNING, OF CHRISTIANIA, NORWAY.

PROCESS OF PRESERVING EGGS.

SPECIFICATION forming part of Letters Patent No. 709,583, datedSeptember 23, 1902.

} Application filed May 23. 1901. Serial No. 61,639. (No specimens.)

To all whom it may concern:

Be it known that 1, WILLIAM SoHoNINe, a subject of the King of Swedenand Norway, residing at Ohristiania, Norway, have invented a new anduseful Improved Process of Preserving Eggs, of which the following is adescription.

The present invention consists of .a process for preserving eggs.

In order to attain the object in view according to the present inventionthe fresh eggs are first laid in hot water (not boiling water) for a fewseconds. Immediately after they have been removed from the warm waterthey are placed in asolution of cold saltwater, sal-ammoniac, andsilicate of soda and allowed to remain in the same until they havebecome quite cold. The proportions of the solution are advantageouslyeighty parts, by weight, of cold salt water, ten parts of salammoniac,and ten parts of silicate of soda.

The result of this treatment is that the hot water or steam sterilizesthe contents of the egg without, however, imparting to them the taste orappearance of a boiled egg. The skin within the shell of the egg is alsothoroughly sterilized and rendered stronger, so that it will be moreimpervious to the outer air. During the heating or Warming process thepores of the egg are opened, while the cold solution mentionedimmediately sets in the pores and provides a coating over the shell,which renders it also impervious to the influences of the atmosphere.This treatment has the effect of forming a thin coating over the shellof the egg, which closes up all the pores of the same, preventing theatmospheric air from penetrating the shell. Eggs treated in thismannerwill keep fresh for any length of time.

If the eggs are intended for export to countries having a hot climate,it is advantageous to allow them to remain somewhat longer in the warmwater before they are placed in the solution as above described.

I claim as my invention- Process for preserving eggs, which consists infirst warming the fresh eggs in Warm water for a few seconds and thenimmediately they are removed from the warm water, allowing them to coolin a solution of cold salt water, sal-ammoniac, and silicate of soda, inthe manner and for the purpose substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
